DETAILED DESCRIPTION

[0017] like Figures 1 to 3As shown, a device for correcting the deviation of the head and tail of a stainless steel coil comprises a mounting frame 1 and a centering mechanism, wherein a roller 2 is rotatably arranged on the mounting frame 1, and the centering mechanism comprises two centering frames 3, which are symmetrically arranged at both ends of the roller 2, and a centering rolling roller 4 is rotatably connected to the centering frame 3, and the centering frame 3 has the freedom to move along the axial direction of the roller 2. The two centering frames 3 move in opposite directions, and the stainless steel coil is supported by the roller 2. The stainless steel coil passes through the two centering rolling rollers 4 when the head of the strip is threaded or the tail of the strip is swung off, and then the positions of the two centering rolling rollers 4 are adjusted so that the two centering rolling rollers 4 contact the two side walls of the strip respectively, thereby limiting the movement of the strip and correcting the deviation. The structure is simple, the operation is convenient, the use effect is good, and the cost is low. Preferably, a driving cylinder 14 is provided at one end of the detection seat 5 away from the centering frame 3, the cylinder body of the driving cylinder 14 is installed on the mounting frame 1, and the telescopic shaft of the driving cylinder 14 is connected to the detection seat 5. The detection seat 5 and the centering rolling roller 4 are driven to move closer to or away from the stainless steel strip through the telescopic movement of the driving cylinder 14, so as to adjust the distance between the two centering rolling rollers 4 according to the width of the stainless steel strip.

[0018] Furthermore, if Figure 1 and Figure 2 As shown, a detection seat 5 is provided at the end of the centering frame 3 away from the roller 2, and a telescopic shaft 7 is provided between the detection seat 5 and the centering frame 3. A pressure sensor 6 is embedded in the end of the detection seat 5 close to the centering frame 3. One end of the telescopic shaft 7 is connected to the centering frame 3, and the other end contacts the pressure shaft of the pressure sensor 6. When the offset force of the web is too large, the force between the centering rolling roller 4 and the web will gradually increase, which may easily cause damage to the web and product quality problems. Therefore, the contact pressure between the web and the centering rolling roller 4 is detected by the pressure sensor 6. When the pressure detected by the pressure sensor 6 reaches the set value, the threading or tail swinging operation of the stainless steel web is stopped, and the staff will detect the equipment condition and solve the problem of increased pressure caused by the inability to correct the deviation of the stainless steel web before continuing production, thereby protecting the stainless steel web and avoiding crushing or damage.

[0019] Furthermore, sliding rods 9 are provided on both sides of the telescopic shaft 7, one end of the sliding rod 9 is connected to the centering frame 3, and the other end is slidably passed through the detection seat 5, and a spring 10 is provided between the detection seat 5 and the centering frame 3. The spring 10 is sleeved on the sliding rod 9, and the two ends of the spring 10 are respectively connected to the centering frame 3 and the detection seat 5. The centering frame 3 and the detection seat 5 are connected together through the sliding rod 9, and the centering frame 3 can move relative to the detection seat 5, thereby protecting the stainless steel tape.

[0020] Furthermore, if Figures 1 to 3As shown, the telescopic shaft 7 includes a pressure shaft 15 and a sliding shaft 16. One end of the pressure shaft 15 contacts the pressure shaft of the pressure sensor 6, and the other end is slidably penetrated by the sliding shaft 16. The end of the sliding shaft 16 away from the pressure shaft 15 is connected to the centering frame 3. The side wall of the sliding shaft 16 is provided with a tapered hole 11, and the side wall of the pressure shaft 15 is slidably penetrated by a limiting cone 12. When the spring 10 is in normal state, the tapered hole 11 is located on the moving path of the limiting cone 12. The side wall of the pressure shaft 15 is installed with a cylinder 13. The telescopic shaft of the cylinder 13 penetrates into the pressure shaft 15 and connects to the limiting cone 12. The cylinder 13 drives the limiting cone 12 to fit into the tapered hole 11, so that the pressure shaft 15 is connected to the sliding shaft 16, so that the telescopic shaft 7 cannot be extended or retracted. At this time, the pressure of the stainless steel strip on the centering rolling roller 4 will be The telescopic shaft 7 acts directly on the pressure sensor 6, thereby accurately reflecting the contact pressure between the stainless steel strip and the centering rolling roller 4. When the actual contact pressure is greater than the set value on the pressure sensor 6, the cylinder 13 drives the limiting cone 12 to disengage from the tapered hole 11, unlocking the sliding shaft 16, so that the sliding shaft 16 can move in the pressure shaft 15. The telescopic shaft 7 is extended and retracted to enable the centering frame 3 to move closer to the detection seat 5, thereby preventing the pressure between the stainless steel strip and the centering rolling roller 4 from continuing to increase, thereby protecting the stainless steel strip. When the offset problem of the stainless steel strip is manually resolved, the centering frame 3 is reset under the reaction force of the spring 10. At this time, the tapered hole 11 is located on the moving path of the limiting cone 12, and the cylinder 13 drives the limiting cone 12 to insert into the tapered hole 11 to complete the limiting of the sliding shaft 16.
